I had planned to do a vlog of putting together my bookcases and organizing them by color vertically rather than horizontally. I thought a tutorial would be fun, but my laptop broke, which meant I didn't have a webcam to use and I didn't want Luke filming me with the iPhone, so I decided to just do pictures.
After Luke put the shelves together, sans cat-pee-ruined portions
All the bookcases put together and in place. Yay Smart Shelves!
Gather all books of the same color and order them in the color direction you want them to go. Mine start with light pink, move to red, then orange, yellow, green, blue, and purple. So I started by gathering all my pinks from lightest to darkest.
